Linearly polarized cascaded Raman fiber laser with random distributed feedback operating beyond 1.5 μm. Lobach, I. A., Kablukov, S. I., & Babin, S. A. Optics Letters, 42(18):3526–3529, September, 2017. Publisher: Optica Publishing Group
Paper doi abstract bibtex We report on, to the best of our knowledge, the first demonstration of a linearly polarized cascaded Raman fiber laser based on a simple half-open cavity with a broadband composite reflector and random distributed feedback in a polarization-maintaining phosphosilicate fiber with a zero dispersion wavelength at ∼1400 nm. Pumped by a 1080 nm Yb-doped fiber laser, the random laser delivers more than 8 W at 1262 nm and 9 W at 1515 nm with a polarization extinction ratio of 27 dB. The generation linewidths amount to about 1 and 3 nm, respectively, being almost independent of power, in correspondence with the theory of a cascaded random fiber lasing.
